FIELD

This invention relates to the technical field of belt accessories, in particular, a belt buckle.

BACKGROUND

With the pursuit of beauty, people show increasing love for diversified clothing accessories. Therefore, single-sided belts can no longer meet people's needs. As a result, two-sided belts emerge at the right moment. With two-sided belts, people can change the visible side of their belt to match with their clothes to show a different visual effect. However, at the present, changing the visible side of a belt is finished by rotating the tail clamp of the belt. The rotating tail clamps in the market adopt intermediate rotating shaft structure. There are corresponding concave and convex on the tail clamp and front end. A spring is set in the middle of the rotating shaft and the tail end is fixed with nut or screwed for fixing with glue. When it is necessary to rotate, pull up the tail clamp to squeeze the spring and pull out the tail clamp from the groove that is connected with the front end. Rotate for 180 degrees until the concave and convex matches and allow the tail clamp to restore to correspond with the front end under the force of the spring, and thus realizing flexible switchover of the two sides of the belt body. However, this method has the following deficiencies:

1. The nut, whether with glue applied or not, will come off after being used for a long time, and thus needing repair. 2. The spring will weaken or loosen or break after being used for a long time. If the nut is fixed by welding, the nut will not come off, but the spring tends to break more quickly under high temperature. 3. During use, the tail clamp is often pulled open under force and clips on the clothes or skin while the life of the spring is also affected under force.

Therefore, there is an urgent need in the industry for a structure that only needs spring and nut to realize flexible switchover of the two sides of belt body.
